Creating a PCB in Everything

10 Articles

For the last five months, I’ve been writing a series of posts describing how to build a PCB in every piece of software out there. Every post in this series takes a reference schematic and board, and recreates all the elements in a completely new PCB tool.

There are three reasons why this sort of review is valuable. First, each post in this series is effectively a review of a particular tool. Already we’ve done Fritzing (thumbs down), KiCad (thumbs up), Eagle (thumbs up), and Protel Autotrax (interesting from a historical perspective). Secondly, each post in this series is a quick getting started guide for each PCB tool. Since the reference schematic and board are sufficiently complex for 90% of common PCB design tasks, each of these posts is a quick how-to guide for a specific tool. Thirdly, this series of posts serves as a basis of comparison between different tools. For example, you can do anything you want in KiCad and most of what you want in Eagle. Fritzing is terrible, and Autotrax is the digital version of the rub-on traces you bought at Radio Shack in 1987.

With that introduction out of the way, let’s get cranking on Upverter.

A little bit about Upverter

Upverter was founded in 2010 as an entirely web-based EDA tool aimed at students, hobbyists, and Open Hardware circuit designers. This was one of the first completely web-based circuit design tools and Upverter’s relative success has been a bellwether for other completely web-based EDA tools such as circuits.io and EasyEDA.

I would like to take a second to mention Upverter is a Y Combinator company (W11), which virtually guarantees this post will make it to the top of Hacker News. Go fight for imaginary Internet points amongst yourselves.

Upverter is a business after all, so how are they making money? Most EDA suites offer a free, limited version for personal, hobbyist, and ‘maker’ projects, and Upverter is no exception. The professional tier offers a few more features including CAM export, 3D preview, an API, simulation (coming soon), BOM management, and unlimited private projects for $125 per seat per month, or $1200 per seat per year.

To give you a basis of comparison for that subscription fee, Eagle CAD’s new license scheme gives you everything – 999 schematic sheets, 16 layers, and unlimited board area – for $65 per month, or $500 per year. Altium’s CircuitStudio comes in at $1000 for a one-year license. There are more expensive EDA suites such as Altium Designer and OrCAD, but you have to call a sales guy just to get a price.

Upverter is positioning itself as a professional tool at a professional price. There are better tools out there, of course, but there are thousands of businesses out there designing products with tools that cost $500 to $1000 per seat per year. In any event, this is all academic; the Hackaday crowd gravitates towards the free end of the market, whether that means beer or speech.

A big draw for Upverter is their Parts Concierge service. You’ll never have to create a part from scratch again, so the sales copy says. Apparently, Upverter is using a combination of very slick scripts to pull part layouts off a datasheet and human intervention / sanity check to create these parts. Does it work? We’re going to find out in the review below.

This is the continuation of a series of posts where I create a schematic and PCB in various EDA tools. Already, we’ve looked at Eagle CAD, KiCad, and took a walk down memory lane with one of the first PCB design tools for the IBM PC with Protel Autotrax. One of the more controversial of these tutorials was my post on Fritzing. Fritzing is a terrible tool that you should not use, but before I get to that, I need to back up and explain what this series of posts is all about.

The introduction to this series of posts laid it out pretty bare. For each post in this series, I will take a reference schematic for a small, USB-enabled ATtiny85 development board. I recreate the schematic, recreate the board, and build a new symbol and footprint in each piece of software. That last part — making a new symbol and footprint — is a point of contention for Fritzing users. You cannot create a completely new part in Fritzing. That’s a quote straight from the devs. For a PCB design tool, it’s a baffling decision, and I don’t know if I can call Fritzing a PCB design tool now.

For our KiCad tutorials, we’ve already done the basics. We know how to create a PCB, make a part from scratch, and turn that into a board. This is the bare minimum to be considered competent with KiCad, but there’s so much more this amazing tool has to offer.

In part three of this KiCad tutorial, we’re going to take a look at turning our board into Gerbers. This will allow us to send the board off to any fab house. We’re going to take a look at DRC, so we can make sure the board will work once we receive it from the fab. We’re also going to take a look at some of the cooler features KiCad has to offer, including push and shove routing (as best as we can with our very minimalist board) and 3D rendering.

This is the continuation of a series where I create a PCB in every software suite imaginable. Last week, I took a look at KiCad, made the schematic representation for a component, and made a schematic for the standard reference PCB I’ve been using for these tutorials. Now it’s time to take that schematic, assign footprints to parts, and design a circuit board.

This is the continuation of a series of articles demonstrating how to Create A PCB In Everything. In this series, we take a standard reference circuit and PCB layout — a simple ATtiny85 board — and build it with different PCB design tools. Already, we’ve taken a look at the pre-history of PCB design with Protel Autotrax, we learned Fritzing is a joke for PCB design, and we’ve done a deep dive into Eagle. Each of these tutorials serves two purposes. First, it is a very quick introduction to each PCB design tool. Second, this series provides an overall comparison between different PCB design tools.

Now, finally, and after many complaints, it’s time for the tutorial everyone has been waiting for. It’s time for KiCad.

No, like the head of the Bajoran clergy

Although KiCad (pronounced ‘Kai-Cad’ like the head of the Bajoran clergy, not ‘Key-Cad’ like the thing that goes in a lock)is the new hotness when it comes to PCB design. The amazing growth of KiCad installations over the past few years is a long time coming. In development since 1992, KiCad has cemented itself as the premier Open Source PCB design suite, and since 2013 CERN has been making contributions to the project. More recently, the KiCad project has been showing off some amazing new features. These include 3D rendering of boards, interactive routing, push-and-shove, simulation, and dozens of other features that put it on a path to being on par with the top of the line EDA suites. Add in some great community contributions, and you have something really, really amazing. All of this is wrapped up in an Open Source license, free as in speech and beer. If you’re looking for the future of PCB design, Eagle is going to get very good but KiCad is almost there now while being Open Source.

Protel Autotrax is a PCB design tool first released for DOS in the mid-80s. Consider this a look at the history of PCB design software. I’m not recommending anyone actually use Protel Autotrax — better tools with better support exist. But it’s important to know where we came from to understand the EDA tools available now. I’m rolling up my sleeves (about 30 years worth of rolling) and building our standardized test PCB with the tool. Beyond this, I suggest viewing EEVblog #747, where [Dave] digs into one of his old project, Borland Pascal, and Protel Autotrax.

This is the continuation of a series of articles demonstrating how to Create A PCB In Everything. In this series, we take a standard reference circuit and PCB layout — a simple ATtiny85 board — and build it with different PCB design tools. We’ve already covered Eagle in this series. We learned Fritzing is a joke for PCB design, although it is quite good for making breadboard graphics of circuits. Each of these tutorials serves as a very quick introduction to a specific PCB design tool. Overall, this series provides for a comparison between different PCB design tools. Let’s dig into Protel Autotrax.

A short history of Protel, Altium, and Autotrax

The company we know as Altium today was, for the first fifteen years of its existence, known as Protel. Back in the day, PCB design on a computer required a dedicated workstation, a lot of hardware, light pens, and everything was extraordinarily expensive. Protel was a reaction to this and the first product, Autotrax, was a DOS-based program that brought PCB design to the PC. A freeware version of Autotrax is still available on the Altium website and can be run from inside a DOS virtual machine or DOSBox.

Interestingly, Protel Autotrax is not the only PCB design software named Autotrax. A company called DEX 2020 has also has a PCB design software called AutoTRAX. This is weird, confusing, and I can’t figure out how this doesn’t violate a trademark. If anyone has any insight to what the Protel / Altium legal department was doing a few decades ago, your wisdom is welcome in the comments.

This week, we’re continuing our Creating A PCB In Everything series, where we go through the steps to create a simple, barebones PCB in different EDA suites. We’re done with Eagle, and now it’s time to move onto Fritzing.

Fritzing came out of the Interaction Design Lab at the University of Applied Sciences of Potsdam in 2007 as a project initiated by Professor Reto Wettach, André Knörig and Zach Eveland. It is frequently compared to Processing, Wiring, or Arduino in that it provides an easy way for artists, creatives, or ‘makers’ to dip their toes into the waters of PCB design.

I feel it is necessary to contextualize Fritzing in the space of ‘maker movement’, DIY electronics, and the last decade of Hackaday. Simply by virtue of being an editor for Hackaday, I have seen thousands of homebrew PCBs, and tens of thousands of amateur and hobbyist electronics projects. Despite what the Fritzing’s Wikipedia talk page claims, Fritzing is an important piece of software. The story of the ‘maker movement’ – however ill-defined that phrase is – cannot be told without mentioning Fritzing. It was the inspiration for CircuitLab, and the Fritzing influence can easily be seen in Autodesk’s 123D Circuits.

Just because a piece of software is important doesn’t mean it’s good. I am, perhaps, the world’s leading expert at assessing poorly designed and just plain shitty PCBs. You may scoff at this, but think about it: simply due to my vocation, I look at a lot of PCBs made by amateurs. EE professors, TAs, or Chris Gammell might beat me on volume, but they’re only looking at boards made by students using one tool. I see amateur boards built in every tool, and without exception, the worst are always designed in Fritzing. It should be unacceptable that I can even tell they’re designed in Fritzing.

Fritzing has its place, and that place is building graphical representations for breadboard circuits. Fritzing has no other equal in this respect, and for this purpose, it’s an excellent tool. You can also make a PCB in Fritzing, and here things aren’t as great. I want to do Fritzing for this Creating A PCB In Everything series only to demonstrate how bad PCB design can be.

For the next few thousand words, I am going to combine a tutorial for Fritzing with a review of Fritzing. Fritzing is an important piece of software, if only for being a great way to create graphics of breadboard circuits. As a PCB design tool, it’s lacking; creating parts from scratch is far too hard, and there’s no way to get around the grid snap tool. No one should ever be forced to create a PCB in Fritzing, but it does have its own very limited place.
